MOORING DEVICE

PROBLEM TO BE SOLVED: To provide a mooring device capable of improving a braking force when a traveling body is moored and maintaining the braking force even if loss of power occurs, in the mooring device for mooring the traveling body such as a crane traveling along a rail.SOLUTION: A mooring device 1 includes: a wheel collision part 2 facing a movement direction of a wheel of a traveling body; a back face 3 located on a side opposite to the wheel collision part 2; grip parts 4 connected to the wheel collision part 2 and holding both faces of a rail 20, respectively; and brake shoes 5 each disposed between the grip part 4 and the rail 20. The grip part 4 includes an inclined face 9 separated from the rail 20 from the wheel collision part 2 side toward the back face 3 side. The brake shoe 5 is formed so as to become thicker along the inclined face 9 from the wheel collision part 2 side toward the back face 3 side, and is arranged slidably in the longitudinal direction of the rail 20 relative to the grip part 4.
